Abstract
Theory and experimental evidence of a new transient polarization phenomenon, unique to sawtooth superlattices, are presented. This effect is the consequence of the lack of reflection symmetry in these structures and can be used for the implementation of a new class of high-speed, displacement current photodetectors.Keywords
